This projector was used by a Canadian nun to show slides of her work and travels in the Far East (Asia). - Function
-
Machine takes two slides and allows fade-out of one and illumination of other. - Technical
-
The two projector lenses allowed the user to "dissolve" between slides by alternating which lens received light. This allowed for a more continuous presentation by allowing the presenter to reload the shaded lens, as the other was active. This innovation was meant to replace the multiple slot slide carriers, which would have to be reloaded and interrupt the flow of a presentation. - Area Notes
